In a groundbreaking study led by the University of Pittsburgh School of Medicine and UPMC,researchers have discovered that exposure to long-wavelength red light significantly reduces blood clot formation in both mice and humans. This innovative approach could revolutionize clot prevention,potentially saving millions of lives worldwide.
The Science Behind Red Light Therapy
Blood clots are a leading cause of preventable death, contributing to conditions like heart attacks, strokes, and lung damage. The study, published in the Journal of Thrombosis and Haemostasis, reveals that red light exposure reduces inflammation and platelet activation—key drivers of clot formation.
To test their hypothesis, researchers exposed mice to 12 hours of red, blue, or white light, followed by 12 hours of darkness, in a 72-hour cycle. The results were striking: mice exposed to red light had nearly five times fewer blood clots than those exposed to blue or white light. Importantly, activity, sleep, eating, weight, and body temperature remained consistent across all groups, suggesting that red light specifically targets clot-promoting mechanisms without disrupting normal bodily functions.
“The light we’re exposed to can change our biological processes and change our health,” said lead author Elizabeth Andraska, M.D., assistant professor of surgery at Pitt’s Trauma and Transfusion Medicine Research Center and vascular surgery resident at UPMC. “Our findings could lead to a relatively inexpensive therapy that would benefit millions of people.”
Human Connection and Future Applications
The study also found a connection between red light exposure and reduced clot risks in humans. As an example, cancer patients using blue light-filtering lenses showed lower rates of blood clots. This finding underscores the potential for red-light-based interventions, such as specialized goggles, to prevent clots in high-risk populations.
Researchers are now developing red-light-based devices to explore therapeutic applications. If clinical trials confirm these findings, this approach could offer a non-invasive, cost-effective solution to a global health crisis.

Red Light Therapy: A Breakthrough in Reducing Blood Clot Risk
A groundbreaking study led by researchers at the University of Pittsburgh and Washington University in st. Louis has uncovered a surprising connection between light exposure and blood clot formation. Published in the Journal of Thrombosis and Haemostasis, the research reveals that red light exposure may significantly reduce the risk of blood clots, particularly in high-risk populations like cancer patients.
The Science Behind Light and Clotting
The study analyzed data from over 10,000 patients who underwent cataract surgery. Some received conventional lenses that transmit the full visible light spectrum, while others were fitted with blue light-filtering lenses, which block about 50% of blue light. The findings were striking: cancer patients with blue light-filtering lenses had a lower risk of blood clots compared to those with conventional lenses.
“These results are unraveling a fascinating mystery about how the light to which we’re exposed on a daily basis influences our body’s response to injury,” said senior author Matthew Neal, M.D., professor of surgery and co-director of the Trauma and Transfusion Medicine Research Center at Pitt.
The team discovered that the optic pathway plays a crucial role. Light wavelength had no effect on blind mice, and shining light directly on blood samples also failed to alter clotting. This suggests that the eyes are the gateway for light’s impact on the body’s clotting mechanisms.
Red Light’s anti-Clotting Effects
Red light exposure was associated with reduced inflammation and immune system activation. Mice exposed to red light produced fewer neutrophil extracellular traps (NETs), web-like structures that trap platelets and contribute to clot formation. Additionally, red light increased fatty acid production, which reduces platelet activation—a key factor in clot formation.
“Our next steps are to figure out why, biologically, this is happening, and to test if exposing people at high risk for blood clots to more red light lowers that risk,” Neal explained. “Getting to the bottom of our revelation has the potential to massively reduce the number of deaths and disabilities caused by blood clots worldwide.”
Preparing for Clinical Trials
The research team is now developing red light goggles to control light exposure in study participants. These goggles will help determine who stands to benefit most from red light therapy.The ultimate goal is to translate these findings into practical treatments, such as medications or therapies that mimic red light’s effects without requiring continuous exposure.
Key Findings at a Glance
| Key Insight | Details |
|————————————-|—————————————————————————–|
| Blue Light-Filtering Lenses | Cancer patients with these lenses had a lower risk of blood clots. |
| Red Light Exposure | reduces inflammation, immune activation, and platelet trapping. |

How Red Light Therapy Could Revolutionize Thrombosis Prevention
A groundbreaking study reveals that altering visible light exposure can significantly modulate platelet function and regulate thrombus formation. This discovery opens new doors for non-invasive therapies targeting thrombosis, a leading cause of cardiovascular diseases worldwide.
The Science Behind Light and Thrombosis
The study, conducted on wild-type C57BL/6J mice, explored how different light spectra—ambient, blue, and red—effect platelet activity and thrombosis. Mice were exposed to ambient light (400 lux), blue light (442 nm, 1400 lux), or red light (617 nm, 1400 lux) for 72 hours under a 12:12 hour light-dark cycle.
the results were striking. Exposure to long-wavelength red light led to reduced platelet aggregation and activation. While RNA-seq analysis showed no significant transcriptomic changes between mice exposed to red light (micered) and ambient light (micewhite), global metabolomic changes were observed in platelets from micered.
Key Findings
- Reduced Platelet Activation: red light exposure decreased platelet aggregation and activation, a critical factor in preventing thrombosis.
- Lower Neutrophil Extracellular Trap Formation: Releasate from activated platelets in micered resulted in reduced neutrophil extracellular trap formation, a key driver of thrombosis.
- Improved Outcomes in Stroke and VT Models: Micered exhibited reduced venous thrombosis (VT) weight and smaller brain infarct sizes following stroke.
Translating Findings to Human Health
To validate these findings in humans, researchers analyzed data from cataract patients over an 8-year period.Patients with a history of cancer who received light-filtering lenses had a lower lifetime risk of venous thromboembolism. This suggests that filtering low-wavelength light could offer protective benefits against thrombosis.
Implications for Light Therapy
The study concludes that light therapy, particularly red light, could be a promising approach to thrombus prophylaxis. By targeting the intersection between innate immune function and coagulation, this non-invasive method could revolutionize how we prevent and treat thrombosis.
Summary Table
| Key aspect | Findings |
|——————————|—————————————————————————–|
| Red Light Exposure | reduced platelet aggregation and activation |
| Metabolomic Changes | Global changes observed in platelets from micered |
| Neutrophil Extracellular Traps | Reduced formation in micered |
| Human Application | Lower venous thromboembolism risk in cataract patients with light-filtering lenses |
This research underscores the potential of light therapy as a novel, non-invasive strategy for thrombosis prevention. As scientists continue to explore the mechanisms behind these findings, the future of cardiovascular health may shine brighter than ever.
Mice and human blood samples, found that red light exposure reduced the formation of neutrophil extracellular traps (NETs), which play a critical role in clot formation. nets are web-like structures released by neutrophils, a type of white blood cell, that trap platelets and promote clotting. By reducing NET formation, red light therapy could help prevent hazardous blood clots.
Additionally, red light exposure was shown to increase the production of fatty acids, which further reduces platelet activation—a key step in the clotting process. This dual mechanism suggests that red light therapy could be a powerful tool in preventing thrombosis, particularly in high-risk populations such as cancer patients, who are prone to clotting due to their condition and treatments.
How Light Exposure Affects Clotting
The researchers discovered that the eyes play a crucial role in mediating the effects of light on clotting. In experiments with blind mice, light exposure had no impact on clotting, and shining light directly on blood samples also failed to alter clotting. This suggests that the optic pathway—the way light signals are transmitted from the eyes to the brain—is essential for light’s anti-clotting effects.
This finding is particularly intriguing because it highlights the interconnectedness of our sensory systems and physiological processes.It also opens up new avenues for research into how other forms of light therapy might influence various bodily functions.
Potential Applications of Red Light therapy
The implications of this research are vast. If red light therapy proves effective in clinical trials,it could become a cornerstone of preventive medicine,offering a non-invasive,low-cost solution to reduce the risk of blood clots. This could be especially beneficial for:
- Cancer Patients: Many cancer patients are at high risk for blood clots due to their disease and treatments like chemotherapy. Red light therapy could provide a safe and effective way to reduce this risk.
- Post-Surgical Patients: Patients recovering from surgery are frequently enough at risk for clots due to immobility. Red light therapy could be integrated into post-operative care to prevent complications.
- Individuals with Cardiovascular Disease: People with conditions like atrial fibrillation or deep vein thrombosis could benefit from red light therapy as part of their treatment regimen.
Preparing for Clinical Trials
The research team is now developing red light goggles to control light exposure in study participants. These goggles will allow researchers to precisely measure the effects of red light on clotting in humans. the ultimate goal is to translate these findings into practical treatments, such as medications or therapies that mimic red light’s effects without requiring continuous exposure.
Key Takeaways
- Red Light Reduces Clotting: Exposure to red light reduces inflammation, immune activation, and platelet trapping, all of which contribute to clot formation.
- Eyes Are Key: The optic pathway is essential for mediating light’s effects on clotting, suggesting that light therapy must be delivered through the eyes to be effective.
- Potential for Non-Invasive Therapy: Red light therapy could offer a safe,non-invasive way to prevent blood clots,particularly in high-risk populations.
